fix(issue): runHeadless restarts on deterministic EXIT_ERROR without classification, looping through identical no-work state (headless.js:172)

[jeremymcs]

Summary

• Added deterministic no-work classification to suppress headless restart loops and report no-work-deterministic, verified via targeted headless-events tests.

Bugs Addressed

• Headless restarts deterministic EXIT_ERROR states with no progress
• Final headless status misclassifies deterministic no-work as timeout/error

Verification

• Completed in the repository worktree before push.

Approved review-comment tasks:
None

Approved status-check tasks:
None

Approved documentation tasks:
Documentation updates are required for this PR.
Assessment summary: PR changes headless externally observable behavior and output (`status` now includes `no-work-deterministic`, and restart policy/logging changes), so any docs describing headless result statuses, retry/restart behavior, or operator troubleshooting should be updated to match.
Update the appropriate repository documentation for these changes.
Choose the right docs files for this repository (for example README, docs pages, API/config/operator docs).
If, after inspection, the repository documentation is already accurate or there is no appropriate docs target, leave docs unchanged and report that using the docs summary block with `no_change`.

When done:
1) Run the relevant verification for your changes.
2) Leave any changed files in the worktree for the babysitter app to finalize.
3) For each feedback item you addressed or were blocked on, emit a summary block in the following format:
   FEEDBACK_SUMMARY_START <auditToken>
   <A concise 1-2 sentence summary of what you did or why you were blocked>
   FEEDBACK_SUMMARY_END
   Include one block per audit token. These summaries will be posted as follow-up comments on the PR.
4) If documentation tasks were assigned, emit exactly one docs summary block in the following format:
   DOCS_SUMMARY_START <changed|no_change>
